And when this property convert from default-sample-phase in linux-5.7 by commit 8a385eb57296 ("ARM: dts: rockchip: fix rockchip,default-sample-phase property names"), the emmc on rk3036 kylin board get a initialising error: [ 4.512797] Freeing unused kernel memory: 8192K [ 4.519500] mmc_host mmc1: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0) [ 4.530971] mmc1: error -84 whilst initialising MMC card [ 4.537277] Run /init as init process [ 4.550932] mmc_host mmc1: Bus speed (slot 0) = 300000Hz (slot req 300000Hz, actual 300000HZ div = 0) [ 4.664717] mmc_host mmc1: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0) [ 4.676156] mmc1: error -84 whilst initialising MMC card I think the reason why the emmc on rk3036 kylin board was able to work before linux-5.7 was that the illegal property was not correctly identified by the rockchip dw_mmc driver.
